True confessions time: I went through a phase awhile back where I regularly slept in a bra. I thought the support it lent was more comfortable than the actual comfort of going without, so every night I dutifully put on a bra and then my pajamas before crawling into bed. While I'm not completely sure why I stopped (that's right — I now sleep bra-less), it's entirely possible that it was because of one of the weird things that happen when you sleep in a bra.
Women have varied (and often vehement) opinions on whether wearing a bra while you sleep is good or bad. Some say that it can cause breast cancer (not true), make your breasts sag (also incorrect), and even make them perkier (again, not accurate). All of these claims about wearing bras to bed were debunked by Shape. Essentially, some women wear them because, like my, they believe that the support that well-fitting bras provide is comfortable and some avoid wearing them to sleep because they find bras uncomfortable (or believe in one of the many myths related to the subject). Although sleeping in a bra may not be categorically go or bad across the board, here a few strange things that might happen if you do.
